Specification of Letters Patent. Patented M 28 1922 Application filedFebruary 16, 1818.. Serial No. 217,680.

To all whom it may concern: 7

Be it known that I, KENNETH L. VAN AUKEN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in TruckFrames, of which I do declare the following to be a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

The present invention hasrelation more particularly to the improvementof truck frames for railway motor cars, such for example, as are used bysection gangs, and the object of the invention is to provide anextremely cheap, light and effective construction of truck frame. Tothis end the invention consists of the features of novelty hereinafterdescribed, illustrated in the accompanying drawings and particularlypointed outin the claims at the end ofthisspecification.

Figure 1 is a plan view of a truck frame embodying my invention. frontend view.' Figure 3 is a. view in side elevation. Figure 4: is a View invertical longitudinal section on line 44 of Fig. 1. Figure 5 is a rearendview. an enlarged detail View in vertical section on line 66 ofFig. 1. Figure 7 is an, en-' larged detail view in vertical section online 7+7 of Fig. 1. Fig. 8 is a plan view, parts being broken away,showing a modified form of the invention. Fig. 9 is a view in verticalcross section on line 9-9 of Fig. 8. Fig. 10 is a view in crosssectionon line 10-10 of Fig. 8. I d,

A designates the side bars of the truck frame and across these side barsat the opposite ends thereof extend the wheel axle B and B at the endsof which are the wheels 0, The axles B and B may be tubular axles, theends having fitted and. secured therein short solid sectionsthat passthrough the hubs of the wheels C. The front axle B is mounted insuitable journal boxes D secured to the side bars A adjacent their frontends and as this front axle B is the driving axle, the wheels C at theends thereof will be rigidly secured thereto, the axle being providedwith a pulley D, sprocket wheel,or

the like, to receive motion from themotor W mounted upon the truck. ,Attheir front ends, the side bars .A are connected together by an iron baror strap A, the ends of which are bent and pass around the sides Figure2 is a Figure 6 is of the side bars A and are suitably bolted thereto.Between the front ends of the side bars A-extend the upwardly andinwardly inclined truss members E, the upper ends of these members beingpreferably mortised, as shown in Flg; 2, and being suitably connected,as by bolts e, to the front section F of the seat plank. From the frontend of the seat plank F and from the upper endsof the truss members Eextend downwardly the metal bars or straps E. The upper ends of thesebars E are preferably bent over the front end of the seat plank F (seeFigsal and 4) and are perforated to receive the bolts '6, while thelower ends of the bars E E are bolted, as at e, to the lowerv bar ormember A of the truss. The outer lower ends of the truss members E abutagainst the end portions of the side bars A and are suitably bolted, asat 6 to the lower bar or member A of the truss.

At the rear end of the truck frame, truss barsll extend upwardly andinwardly from blocks a on the ends of the side bars A, the lower ends ofthe truss members E being suitably secured, as at e, to

curely bolted to the side bars A of the truck,v

suitable wooden blocks being mounted on the side bars to receive the endportions of the axle B.

The upper ends of these bars E are bentand overlap the end of the seatplank section F (see Fig. 1) and are connected thereto by the bolts 6while the lower portionsv of the bars E From the rear end ofthe' seatplank section F extend downwardly the verticalbars or rods E areconnected, as by U-bolts e, to the rear axle B.. The extreme lower endsof the verticalbars E are bent inwardly and'forwardly (see Fig. 4:) andare connected, as by bolts 9, to the rear ends of the bars Gr that formthe lower members of two trusses that. extend fromrend to end of thetruck frame adjacentits longitudinal center. The front ends of the barsG are similarly connected by bolts 9 to the inwardly bent lower ends ofthe barsE, as clearly shown in Figs. 2 and A of the dra vings. Each ofof the bars G are connected, bythe bolts" the bars G is preferably anangle bar the bottom flanges of which extend inwardly and on theseflangesmay rest the basevof the motor W. To "thetront and rear ends 5/,g, the ends of the bars G that form the diagonally bracing members ofthe trusses that .e'iztend longitudinally of the truck. The centralportion of each of the'bars G is" formed W'lth'lt' horizontal "part, as-shovvn, and these horizontal parts of the bars Gr horizontal upperportions of the bars G.

In the preferred embodiment offlthe invention'shovvn, the seat plankforms an upper part ofth'e longitudinal truss 'of'the'strud tureJItiWill beseen also that this upper part or member at its'end or endsforms partof the transverse truss or trusses -of the structure, therebygiving great rigidity tli 'ftoi' Y Iii-the modified form illustrated inFigs; 8} and 10. trusses will be provided "as n the form' jofth'einvention jhereifnbeforedescribed. The V truss at the front en dfof thetruck fiframe will comprise upper "members" E (one only beingshovvn inand a lower member 'A-,'as 1n the construction hereinbefore described,

suitable verticalbars or struts} E extending b'et'iv 'n the upperandlovverlmembers; To

c the rdlyand' rearvvardly turned ends 'of t'he o'wer member A of thefron't'truss are fc'oniiect'edthefofivard ends .9 of the timeshares, therearends ofth'ese bars jejiterfding inwardly and beingbonnected,

asby the bolts'g to the upstandingporjtions' ofthe lo'wer inembersG ofthe longitu'gtlinal trusses. Preferablysuitable spacblockss?are'interp'osed between the inwardly turned ends of the truss member new'afforda better support for the jouriialj'boies-Dthrough which pass theends ofthejront:aXle'B.

*In the modified form of the invention shoivn'in' Figs. 8: to 10,"thereartruss is "omitted", the rear end of the seat plank sectionflF being'shown as supported by the bars E that have their upper ends bolted To"the plank sectionF, vhile their lower 'ends are boltedf pin thejconstruction hereiiihefor'edescribedfto' the rear ends of. the

brace barsT extend between and are bolted 'to'the' rear *aiile B and thesi'des' of the of the invention longitudinal truss members G, as clearlyshowininl igs. Sand 10 of the drawings.

The upper longitudinal truss members G will'be the same in constructionasillustrated in Figs. 3 and 4 and Will be similarly bolted to the lowermembersG of the longitudinal trusses.

Other modifications of the invention may be made Without departingfromthe spirit of the invention and features of the invention may beemployed without its adoption as an entirety.

Having thus described my invention, what I claim as newiand' lesire tosecure comprising a frame having axles and carrying Wheels at its frontand rear ends, a vertically disposed, transverse truss atone end of saidframe and a vertically disposed, longitudinal truss extending betweenthe ends of said frame, an upper member of said longitudinaltruss'forming part of said transverse truss.
